Meatball Frittata

Except for soup, pasta, or salad, there's nearly nothing you can cook that is as versatile as the not-so-humble frittata, which is nothing more than an open-faced omelet.   Just about whatever you've got leftover in your frig, including spaghetti you brought home from the Italian restaurant (and definitely the toppings from that box of cold pizza), can be worked into a frittata and turned into a meal that might feed you a couple times or more.  Will you be happy?  I think so.
